Active clinical trials for "Inflammation"

Every night during sleep, there is an accumulation of white blood cells in the closed eye. The closed eye white blood cells are predominantly neutrophils, but there is a small population (3%) of T cells. The effects of these closed eye white blood cells on dry eye disease pathogenesis have yet to be fully elucidated, but preliminary evidence suggests that closed eye neutrophils may have an associated hyperactivity and increased degranulation in dry eye disease that could contribute to epithelial instability. As an anti-T cell therapy, Xiidra offers an opportunity to better understand how the closed eye white blood cells are recruited and activated. This study also seeks to verify the proposed mechanism of action.

i2-D²EFT substudy is an observational cohort nested within the parent D²EFT study (NCT03017872). D²EFT goal is to compare the standard of care second-line antiretroviral therapy in people living with HIV whose first-line non nucleoside reverse transcriptase-based regimen failed, to two simpler regimens. Approximately 1,000 participants will be enrolled in D²EFT. Commencing a second-line ART is an important moment when the level of inflammation in participants may be elevated due to first-line ART failure; this level of inflammation should then decrease with the commencement of a new second-line treatment and would be expected to normalise by 48 weeks of second-line treatment, if successful. The investigators propose to study other factors which can influence the decrease of inflammation. The investigators hypothesise that co-infections may play a role in persistent inflammation. The key-infections of interest will be common frequent infections encounter throughout the world: Human Herpes virus 8, Epstein-Barr virus, Cytomegalovirus and Human papillomavirus, tuberculosis, malaria and other key opportunistic infections. Possible changes of level of inflammation (using the serum level of Interleukin 6) in approximately 200 participants of the D²EFT study will be investigated and measured. The hypothesis is that the presence of other infections than HIV may influence the level of inflammation in participants in therapeutic success.

Background: Heart failure is a serious health condition. Researchers believe inflammation plays a role. They want to see if adding an additional heart drug to a person s treatment can help treat heart failure with preserved ejection fraction (HFpEF). Objective: To learn if chronic inflammation is high in heart failure and if taking dapagliflozin along with the standard of care medicines for 6 months will reduce inflammation and improve heart function in people with HFpEF. Eligibility: People aged 18 and older who have heart failure and qualify for dapagliflozin therapy. Healthy adult volunteers are also needed. Design: Participants will be screened with: Medical history Physical exam Heart function tests X-ray scans of the heart and blood vessels. They may receive medicines to slow their heart rate or make their heart blood vessels bigger. An intravenous (IV) catheter will be placed in their arm to inject contrast. Blood and urine tests Participants will have up to 3 study visits. Some screening tests will be repeated. Participants will take one tablet of the study drug daily for 6 months. -Participants will have an imaging scan of their heart and blood vessels. They will receive a contrast and stress medicine through an IV to view blood supply. Participants will have a stress test that measures exercise ability. They will wear sticky pads on their chest, a blood pressure cuff, and a mask. They will also have a 6-Minute Walk Test. Participants will complete questionnaires about their symptoms and their health. Participants may be on the study for up to 6 months. They will have a follow-up phone call 1 month after treatment ends. ...

SHIFT is a randomized, longitudinal, prospective, blinded, three-arm study to determine the safety and tolerability of Fecal Microbiota Transplant (FMT) in HIV-infected participants on stable antiretroviral therapy (ART).

The primary purpose of this study is to evaluate the acute effects of electronic cigarette (e-cigarette) smoking on measurable biomarkers of platelet function, vascular endothelial function and inflammation in healthy active smokers. 10 healthy subjects, smokers, with no other medical conditions will be included in this study and measurements will be obtained at baseline and after smoking an e-cigarette. The study will contribute to the understanding of the effects of e-cigarettes on cardiovascular physiology, specifically establishing if the use of e-cigarettes increases platelet aggregation and platelet activation when compared to baseline in healthy active smokers, if the use of e-cigarettes decreases brachial artery flow-mediated dilation compared to baseline in healthy active smokers, and to determine the association between biomarkers of inflammation, platelet function, and vascular endothelial function before and after use of e-cigarettes.

Introduction. Ischemic cardiomyopathy is one of the death leading causes in industrialized countries. Up-to-date ESC guidelines recommend a surgical approach (coronary by pass graft) in patients with multivessel coronaropathy, with involvement of left main (LM) or proximal left anterior descending (LAD) artery. In any case, is recommended the use of the internal thoracic artery (ITA) as conduct of choice. In consideration of the very strong evidence supporting the use of ITA, the study objective is to analyze and compare some blood markers collected from ITA blood vs. LAD blood, with the purpose of better understanding the technique benefits from a biological point of view, being the hemodynamic one already evident. Methods. Forty patients scheduled for coronary bypass graft (CABG) surgery at the Cardiac Surgery Unit of European Hospital of Rome will be enrolled. Patients which intervention includes off-pump ITA-LAD anastomosis will be included. For each patient blood sample from ITA and LAD will be collected. On those samples, polymorphonuclear leukocytes and platelets activity, endothelial dysfunction, oxidative stress and inflammatory burden will be analysed. In patients in which a pre-operative coronary CT scan is available, findings will be correlated with atherosclerotic plaque morphology. Expected results. Diseased LAD's blood will have a deranged markers profile compared with ITA's, with augmented inflammatory burden, reduce NO availability and increased platelet activation. In the patients subgroup with available coronary CT scan will be possible to esteem the effective blood mixing and speculate on a possible pharmacological effect of CABG, in terms of dilution of inflammatory burden in the target vessel.

The aim of this study was to evaluate fixed retainers, bonded with either direct or indirect techniques using one- or two-step adhesives, in terms of periodontal status and failure rates.

This study aims to evaluate gingival crevicular fluid Galectin-3 and Interleukin-1beta levels in different grades (B and C) of stage 3 periodontitis, concurrently, and also to investigate their discriminative efficiencies in periodontal diseases. A total of 80 systemically healthy and non-smoker individuals, 20 stage 3 grade C periodontitis 20 stage 3 grade B periodontitis, 20 gingivitis and 20 periodontally healthy were enrolled. Clinical periodontal parameters were recorded and GCF Galectin-3 and interleukin-1 beta total amounts were measured by ELISA. Receiver operating characteristics curve was used for estimating the area under the curve.

Conversion disorders, also called "dissociative disorders" (ICD-10), or "functional neurological disorders" (DSM-5), are a common condition, with a prevalence of 1-10% in medical and surgical inpatients (Toone 1990), and 10-30% in neurology patients (Carson et al. 2000). They are characterized by the presence of symptoms or deficits affecting voluntary motor, sensory, or sensory functions suggestive of a neurological or general medical condition in combination with psychological factors. Functional neurological disorder is currently a diagnosis of elimination and its treatment remains uncodified. A better understanding of the pathophysiology of this disorder is needed to improve the diagnostic and therapeutic approach to this condition. Identifying new biological markers associated with motor symptoms occurring during the course of the functional neurological disorder would allow clinicians to acquire new diagnostic methods, to improve therapeutic means and their specificity and to highlight possible predictive factors of the clinical evolution of this pathology. At the same time, the identification of biological markers associated with motor symptoms will allow the patient to better understand and accept the diagnosis, and thus to better adhere to the proposed treatment.

The aim of this study is to reveal how different forms of milk casein, lactose and moderate breakdown of proteins affect the symptoms that may arise from milk and markers of inflammation in volunteers receiving symptoms from milk. Research hypotheses are: 1) Protein hydrolyzed milk is as tolerated or better tolerated than A2 milk, and 2) Lactose is the main causative agent of stomach symptoms in milk-sensitive individuals.
